I've been experiencing a similiar problem. Just spoke to Atari Account & Billing support and they said it needed to be escalated to the next tier. Wondering when I'll hit endgame and get this resolved. :p
Anyways, my in game counter says 383, and it has for several months (I remember noticing it well before the 300 day vet rewards were handed out). And on my account, it says 336 days. BS!! Should be at 394 days by my record.
